Definitions

  • the invention relates to an industrial truck, in particular a front seat forklift according to the preamble of claim 1.
  • An industrial truck of the type mentioned is known from DE 196 50 338.
  • the driver's seat is about an axis of rotation that runs far to the front in the footwell, swiveling. With the help of such a measure it should be achieved that the Driver ergonomically occupies a more favorable position when reversing. Improved this measure is further characterized by the fact that the brake pedal is pivotally mounted to approximately the pedal rod, also for an adjustment to get to the driving situation.
  • the known arrangement has some disadvantages on. When the seat is turned, the driver automatically comes into an unfavorable position Position to the steering wheel. He is restricted in his freedom of movement. All in all can lead to ergonomically unfavorable steering.
  • the invention is based on the object of an industrial truck, in particular a front seat forklift, to create, on the one hand driver's seat, pedal arrangement and steering wheel mi can be optimally adjusted with regard to the individual driver, on the other hand when the driver's seat is adjusted, these units position one another maintained.
  • the units namely the driver's seat, Pedal arrangement and bearings for the steering shaft can be moved or adjusted separately.
  • the driver's seat is around an axis of rotation within the seat contour, but is off-center rotatable or pivotable to the center of gravity or center, and pedal arrangement and Steering bearings can be moved along curved curves, the curves being such are arranged that the movable units within a limited angular range are aligned approximately to each other.
  • the construction according to the invention has the advantage that in each pivotable Position of seat, pedal arrangement and steering at approximately the same distance for the Are drivers. As a result, the driver can always adopt the same posture regardless of the position of the units. Another advantage however, is that the units compared to previously known systems can be adjusted independently and therefore to the size of the driver can be adjusted.
  • the construction according to the invention is based on an embodiment of the invention a synchronous circuit of the units is provided, which manages that at a Pivoting of the driver's seat, the other two units are also synchronously pivoted become. Independently of this, each unit can, as mentioned, be set on its own become.
  • the individual units have travel or Adjustment drives, which are preferably formed by electric motors can drive a pinion via a gearbox with an arched toothing or the like cooperates.
  • the drives are according to a further embodiment the invention is preferably self-locking, so that a locking is not necessary in the individual positions taken, as is the case in DE 195 12 284 is described. It goes without saying that the drives are also hydraulic, can act mechanically or in another way.
  • the invention has the further advantage that by pivoting the steering wheel unit there is an optimal entry and exit option.
  • the pedal arrangement be pivoted.
  • the seat can be turned by about 15 ° be additionally pivoted in order to leave or close the device without problems climb. This ensures that the driver's seat is suitable for the disabled.
  • the units are pivoted along predetermined curves. It is but advantageous if all three units have a common pivot point, thus the units have the specified relationship to one another in any angular position exhibit.
  • FIGS. 1 to 7. An overall representation of an industrial truck cannot be found in FIGS. 1 to 7.
  • an industrial truck can be provided, as is basically the case is known for example from DE 196 50 338. It is a so-called Front seat forklift.
  • the driver's seat as shown at 10 in Fig. 1 and in Fig. 2 is indicated, but is arranged somewhat off-center, and a little more to entry on the left.
  • the driver's seat has a seat part 12 and a backrest 14, which is shown in Fig. 1 in two different positions. In Fig. 2 shows the seat part transparent or taken away to the one below Make construction visible.
  • a so-called joystick 16 arranged with the essential Functions of the industrial truck are activated.
  • the joystick is over a bracket 18 attached to the frame of the driving seat, on the front right Side of the seat part 12.
  • a sheet metal plate 20 is screwed onto the base (battery box) for the driver's seat 10.
  • a somewhat thicker plate 22 made of plastic is attached to the plate 20. It has a sector shape, as can be seen from FIG. 2.
  • a gusset section protrudes the area of the seat part forward from when the seat is in the position shown in FIG neutral position.
  • the Tarpaulin 22 a lower arcuate recess 24 on a sheet metal plate 26 with the frame of the seat part 12 is fixedly connected via an axis of rotation 28 which is in the Area of the right front corner of the seat part 12 is arranged, pivotally mounted.
  • an arcuate angle plate 30 On the tarpaulin 26 is an arcuate angle plate 30, which is to guide and Stability purposes engages in the recess 24 and prevents the seat after from tipping.
  • a toothed segment 32 is connected, which with a pinion 34 is engaged which can be driven by a motor gear unit 36.
  • the motor is an electric motor and the motor gear unit 36 is self-locking. By driving with the motor gear unit 36, the seat 20 can therefore by one Be pivoted angle, which is predetermined by the toothed segment 32.
  • the seat 10 is constructed as in Figures 1 and 2 described.
  • a pedal arrangement 54 consisting of an accelerator pedal 56 and a brake pedal 58.
  • the pedals 56, 58 are attached to a holder 60 which can be moved along two curved tracks 62, 66.
  • the cam track 66 has an arcuate slot 68 through which a pin of the holder 60 extends.
  • the cam track 66 is fastened to an upper leg 70 of an angle plate 72 (FIG. 4) which is attached to a wall 74 which delimits the battery box 42 to the left or the foot space 44 to the rear.
  • a toothed segment 76 is also attached to the holder and engages with a pinion of a motor and transmission unit 78 which cannot be recognized and which moves the holder 60 and thus the pedals on an arc. It goes without saying that corresponding slots must be formed in the base plate 46 in order to ensure the movability. These slots can be brushed "to prevent dirt from entering.
  • a steering wheel 80 of the industrial truck is closed recognize whose shaft 82 is rotatably supported in a column 84.
  • column 84 there is a transmission element for transmitting the angle and the angular velocity from the steering wheel to the steering device for the wheels to be steered, as is known in itself.
  • the column is connected to a suitable holder 86 Guide part 88 connected, which is shown in Fig. 6 alone from the back.
  • the Guide part 88 interacts with a guide having two rails 90, 92, which are connected to one another by suitable webs 94 and kept at a distance are.
  • the rails 90, 92 are circular in shape and on attached to the wall portion 50.
  • a Motor gear unit 96 arranged, which cooperates with a toothed segment 98 (FIGS. 6 and 7), which is above the upper guide rail 90 at a distance this is arranged and fastened.
  • a toothed segment 98 FIGS. 6 and 7
  • Fig. 7 are two different positions of the steering wheel 80 are shown.
  • each of the motor gear units Press it is also possible to separately connect each of the motor gear units Press to initially set the relative position of these units to each other or correct later if necessary. It is also conceivable for certain functions to operate only one or two units, for example the steering and bring the pedal assembly into a 45 ° position while the seat is in neutral Steering and pedals can be used to facilitate entry and exit a position pivoted away from the entrance can be pivoted. For improvement the seat can be swiveled in the direction of entry and exit become.
  • FIGS. 8 to 10 show a top view of a front seat stacker. There such a device is generally known, the basic parts are intended in detail are no longer explained. The units that have been described above are shown here together on the truck, in different positions. The units are provided with the same reference numerals as those according to the Figures 1 to 7.
  • Fig. 8 shows the arrangement of the seat 12, steering wheel 80 and pedal assembly 54 for the Forward travel.
  • Fig. 9 shows the arrangement of the seat 10, steering wheel 80 and pedal assembly 54 for reversing.
  • 10 shows the arrangement of seat 10, steering wheel 80 and pedal assembly 54 for getting in and out.
